Told to wander about capital (4)
I believe the answer is:
rome
'capital' is the definition.
(Rome is an example)
'told to wander' is the wordplay.
'told' indicates a 'sounds like' (homophone) clue.
'to wander' becomes 'roam' (synonyms).
'roam' sounds like 'ROME'.
'about' acts as a link.
(Other definitions for rome that I've seen before include "Italian city" , "Seat of Italian empire" , "All roads lead to it" , "The Eternal City" , "Where to emulate the locals" .)
